  2. 1. Color Tuning for Perovskite Light-Emitting Diodes

    Author : Hongling Yu; Feng Gao; Xiaoke Liu; Olle Inganäs; Fengling Zhang; Maksym V. Kovalenko; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskite light-emitting diodes; Color tuning; Pure and mixed halide; Spectral stability; White emission;

    Abstract : Metal halide perovskites (MHPs) are recognized as promising semiconductor materials for a variety of optical and electrical device applications due to their cost-effective and outstanding optoelectronic properties. As one of the most significant applications, perovskite light-emitting diodes (PeLEDs) hold promise for future lighting and display technologies, attributed to their high photoluminescence quantum yield (PLQY), high color purity, and tunable emission color.

  4. 2. Noise sensitivity and FK-type representations for Gaussian and stable processes

    Author : Malin Palö Forsström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; color representation; exclusion process; color process; Noise sensitivity; threshold stable vector; volatility; noise stability; interchange process; threshold Gaussian vector; multivariate stable distribution; Bernoulli random vector; mixing time;

    Abstract : This thesis contains four papers on probability theory. Paper A concerns the question of whether the exclusion sensitivity and exclusion stability of a sequence of Boolean functions are monotone with respect to adding edges to the underlying sequence of graphs. READ MORE

  5. 3. Starch Pickering Emulsions : Process and Encapsulation Stability

    Author : Ali Marefati; Avdelningen för livsmedel och läkemedel; []
    Keywords : Starch granules; Pickering emulsions; Encapsulation; Freeze-thaw stability; Freeze-drying; In vitro digestion; In vitro intestinal lipolysis;

    Abstract : The emulsion stabilization functionality of surfactants and biopolymers can be replaced by solid particles adsorbed at the interface, where they create a category of emulsions known as Pickering emulsions. Recently, health and environmental concerns have led to new market demand for natural, biodegradable and renewable sources of ingredients. READ MORE

  6. 4. Dynamics in Blue Emitting Metal Halide Perovskites for Light Emitting Diodes

    Author : Max Karlsson; Feng Gao; Tze Chien Sum; Barry P. Rand; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perovskites; Light-emitting diodes; Stability; Efficiency;

    Abstract : Lighting comprises a large part of the global electricity consumption as of today, and the use of lighting in illumination and displays is only projected to grow. It is therefore imperative to meet this energy demand, not only by means of greener energy production, but also with materials that are both more efficient to fabricate as well as to use. READ MORE

  7. 5. Color Prediction and Separation Models in Printing : Minimizing the Colorimetric and Spectral Differences employing Multiple Characterization Curves

    Author : Yuanyuan Qu; Sasan Gooran; Roger D. Hersch; Linköpings universitet; []
    Keywords : ;

    Abstract : Color prediction models and color separation models are essential for print device characterization and calibration, from which the profiles used in color management systems are built up. Dot gain refers to the phenomenon in printing causing the printed ink dots appear bigger than their reference size in the original bitmap. READ MORE
